Each face of the two mating CF flanges has a knife edge which cuts into the softer metal gasket, providing an extremely leak-tight, metal-to-metal seal. CF flanges are sexless and interchangeable. The gasket is partially recessed in a groove in each flange. The groove helps hold the gasket in place, which aligns the two flanges and also reduces gasket expansion during bake-out. Available materials for CF flanges are in Stainless Steel 304, 304L, 316, 316L, DIN 1.4301, DIN1.4306, DIN 1.4401, DIN 1.4404.
